sPncIIcATIoN forming part of Letters Patent No. 651,119, dated une 5, 190e. Application led September 17, 1898. Serial No. 691,145; (Nor model.)

of that class in which two pattern cylinders or prisms are employed for cooperation with the needles, each of such pattern cylinders or prisms having its own pattern and the two pattern cylinders or prisms being brought into action in connection with the needles alternately. It is customary to employ this arrangement forweaving goods having end borders or cross-stripes at intervals, one of the pattern cylinders or prisms carrying the pattern for the border or cross-stripe and the other carrying the pattern for the body or intervening portion of the goods.

The invention includes various improved and novel combinations of parts, including devices whereby to bring automatically the respective pattern cylinders or prisms into action alternately at the required times in the working of the jacquard-machine.

The invention will be described iirst with reference to the accompanying drawings, in which latter I have represented one embodiment thereof, after which the invention will be particularly pointed out in the claims at the close of this specification.

Figure 1 of the accompanying drawings shows in side elevation certain .portions of a jacquard-machine of the class aforesaid with the said embodiment of my invention applied thereto, only such parts being represented as are required in order to clearly indicate the nature and relations of the invention. Fig. 2 is a view in vertical transverse section of a jacquard-machine of the said class, showil'g certain of the working parts thereof. Fig. 3 is a view showing certain parts in plan. Figs. 4 and 5 show details on an enlarged scale.

In the drawings, 7l 7l designate certain of the hooks or hooked uprights of a jacquardmachine, the rest of the series being omitted for the sake of securing simplicity and clearthe said needles 1 and 2.

ness. 1 and 2 designate certain needles of the series of needles engaging with said uprights 71 7l, the greater part of the said series of needles being omitted for the reason just stated. The needles 1 2 are arranged and supported in usual manner and engage with the stems of the uprights in customary A fashion, the opposite ends of the said needles being supported in stands 12 and 15 of wellknown character. 16 designates a pattern cylinder or prism arranged to cooperate with Around the said pattern cylinder or prism 16 a series of perforated pattern-cards (not shown) is intended to pass in practice, the said pattern-cards being presented successively against the ends of the needles 1 and 2 by the operation of the pattern cylinder or prism, as will be understood. The intermittent or step-by-step rotation of the pattern cylinder or prism 16 may be occasioned in any preferred manner. I have shown at 43 a pawl of usual character pivoted to the machine-framing and adapted to engage with projections on one end of the said pattern cylinder or prism, as shown, in each outward movement of the latter. 44 designates a reversing-pawl for action in connection with the said pattern cylinder or prism, the same being connected by a rod 45 to pawl 43, as usual.

The invention which is about to be described may be utilized in connection with either a single-action jacquard-machine or a double action jacquard machine. I have illustrated it as embodied in adouble-action jacquard-machine--that is to say, in a jacquard-machine having two sets of moving griit-blades 72 72 and 82 82, respectively, (see Fig. 2,) the said griff-blades being mounted in the gri-frames '7 and 8, respectively, and the said griff-frames being applied to guiderods 18 and 19, which latter` are arranged to slide, as usual, in guides or bearings provided therefor on the frame of the jacquard-machine, the said guides or bearings, however, being omitted from the drawings for the sake of clearness. Movement is communicated to the griEEs through rods 9 and 1() from suitable moving partsof the mechanism, (not shown,) and thereby in usual manner the two griffs are raised alternately. v

IOO

11 designates the usual bottom plate.

A second pattern cylinder or prism is shown at 17, and around the same is intended to pass inpracticeasecondsetofpattern-cards. (Not shown.) The intermittent or step-by-step rotation of the pattern cylinder or prism 17 is or may be eifected, as stated, in connection with the pattern cylinder or prism 1G. Thus the usual actuating-pawl therefor is shown at 42, the reversing-pawl at 41, and the rod connecting these two pawls is designated 46. For convenience the pattern cylinder or prism 17 may be designated the auxiliary cylinder or prism and that designated 16 the main pattern cylinder or prism. Both of the pattern cylinders or prisms serve to actuate the needles 1 2, and thereby control the engagement of the uprights with the moving gri or griifs, although they are not both operative in this respect at the same time. The auxiliary pattern cylinder or prism 17 preferably, as in the drawings, coperates with the needles 1 2 through the medium of a second set of needles, certain of which are shown at 5 6, and which needles may for convenience be designated herein the auxiliary needles, the opposite ends thereof being supported in stands 13 and 1i. Springs 121 121 are shown applied to the various needles l, 2, 5, and G in usual manner and operate to press the said needles toward the respective pattern cylinders or prisms. The auxiliary needles 5 and Gare connected operatively in suitable manner with the needles 1 and 2 for the purpose of enabling the said needles 1 and 2 to be operated when desired by or through the said needles 5 and (i. In some cases the mode of connection may be varied from that herein illustrated. In the present case the needles 1 and 2 are shown connected with the needles 5 and (i by means of levers in the form of wires 3 and 4, which last, respectively, at or near their opposite extremities pass through eyes in the needles l, 2, 5, and 6, each lever or wire 3 or et at its upper extremity passing through an eye of a needle of the auxiliary set 5 G and at its lower extremity passing through an eye of a needle of the main set 1 2. At intermediate points in their length the levers or wires 3 a take bearing against transversely-extending rods 20, the latter constituting fulcra for the said levers or wires when they are moved in consequence of endwise movement of the auxiliary needles 5 and t5. The rods 2O are arranged in an inclined series in supports 21, as shown clearly in Fig. 2, in order that each lever or Wire 3 4 may have its fulcrum-rod 2() located substantially equidistant between the auxiliary needle and main needle with which it coacts. Enlargements or heads 73 73 on the wires or needles 3 and 4 support the latter vertically by resting on the upper sides of the eyes of the auxiliary needles 5 and G. It will be obvious that when one of the auxiliary needles 5 G is moved endwise through the pressure of a blank or unperforated portion of a pattern-card on the auxiliary pattern cyllinder or prism 17 the corresponding needle of the main series 1 2 will be moved endwise through the action of the intermediate Wire or lever of the series 3 4 in precisely the same manner as if such needle of the main series were pressed back by a blank or unperforated part of a pattern-card on the main pattern dylinder or prism 16. Thus the main needles 1 2 and the hooks or uprights 71 71 in engagement therewith may be borne to the left in the drawings through the action of patterncards on either pattern cylinder or prism. So far, therefore, as the matter of determining the engagement of the uprights 71 71 with the moving griff-blades is concerned it is immaterial which ofthe pattern cylinders or prisms is brought into action.

The pattern cylinders or prisms 1G and 17 are mounted, respectively, in carriers or battens 26 27. (See Fig. 1.) The said carriers or battens may be of any approved construction and arrangement. The mode of mounting the same may be varied. Herein the carrier or batten 26 is provided with rods 28, that are iitted to guides 281 281 on the framework 25 of the jacquard-machine, the said rods 28 being arranged to slide horizontally through the said guides. In like manner the carrier or hatten 27 is provided with sliderods 29, that are iitted to guides 291 on the framing 25. With the carriers or battens 26 27 I combine suitable mechanism for operating the same, such mechanism including clutch devices or clutches bymeans of which the respective carriers or battens may bc connected with the said mechanism and disconnected therefrom.` rlhe preferred mechanism consists of reciprocating arms or bars 32 33, hereinafter termed actuators, since their function is to become connected with the carriers or battens and to operate the same. Any suitable arrangement for reciprocating the said actuators simultaneously with each other, but in opposite directions, may be adopted in practice; but I have shown the inner ends of the same connected pivotally with a rocker-arm or rocker 30 at opposite sides of the pivotal stud 48, by means of which the said rocker is mounted on the framing 25 of the jacquard-machine. The said rocker 30 is intended to be operated in practice by any of the means usually employed for actuating the like parts in jacquard-machines. The outer ends of the said actuators are supported by means of pins 361 371, projecting from collars 36 37, respectively, made fast on the slide-rods 28 29, the said outer ends being formed with longitudinally-extending slots 321 331, which receive the said pins. movement of-an actuator the shoulder at the inner end of its slot 321 or 331 in case it encounters the pin 361 or 371 acts against the said pin to force the corresponding carrier outward into the position that is occupied by the left-hand carrier in Fig. l, the carrier ITO During the outward remain-ing in this its idle position so long as it remains unclutched from its actuator. During the time while one of the carriers remains in the said idle position the other carrier remains clutched to its actuator and moves therewith. The clutch that is employed in connection with each carrier consists in the present embodiment of the invention of a simple hook or latch 34 or 35, which is pivoted to the actuator,- as at 341 or 351, adjacent to the slot in the latter. The engagement of the said hook or latch with the pin 361 or 371 is intended to occur when the actuator has reached the outward extreme of its movement, the inner end of the corresponding slot 321 or 331 being then closely adjacent to the said pin, and thereby the said pin is held closely between the said hook or latch and the said inner end of the slot, which causes the carrier or hatten to be moved out and in in unison with the actuator. For the purpose of effecting the engagement and disengagement of the hooks or latches 34 35 with the pins 361 371 and controlling thesame, so as to occasion the operation of the two carriers or battens alternately, I employ in the present instance acontrolling-lever 31, which isshown pivoted upon the stud 48, one arm of the said lever extending under a pin 342, projecting from the hook or latch 34, and the other arm thereof extending under a pin 352, projecting from the hook or latch 35. In one position of the said controlling-lever it holds hook or latch 35 raised out of engagement with pin 371 and permits hook or latch 34 to remain in engagement with pin 361. (See Fig. 1.) The pins 342 352 slide along the plain upper surfaces of the arms of the controlling-lever. In the other position of the controlling-leverit holds the hook or latch 34 raised out of engagement with pin 361 and allows hook or latch 35 to become and remain engaged with pin 371.

In accordance with the present invention I provide automatic pattern devices controlling the clutches and operating the latter to cause the pattern cylinders or prisms to alternate in their Working in connection with the needles. The said pattern devices are connected with the controlling-lever 31 and serve to determine the position thereof, and therethrough to determine which clutch shall be caused to place the corresponding pattern cylinder or prism in operative relations with the actuating mechanism for the pattern cylinders or prisms. Thereby the two carriers for the pattern cylinders or prisms alternately are connected at the required intervals with the said actuating mechanism. In the illustrated embodiment of the invention the controlling-lever 31 is connected by means of a rod 52 with the pattern-lever 51, the latter being hung on the stud or pin 49, affixed to the framing 25. The said pattern-lever is acted upon by a master-pattern 59, passing around a pattern-barrel 53, having connected therewith a ratchet 54. The pattern-chain 59 is advanced at intervals by means of a pawl 56, which is pivoted to one arm of the rocker 30. In connection with pawl 56 I employ a pawl-lifter 57, on which is arranged to bear the pin 58, carried by pawl 56. A spring 60, surrounding the stud or pin 49 and having one end thereof connected with the pawl-lifter 57 and the other end thereof connected with framing 25, serves to hold the pawl-lifter raised normally, so that pawl 5G does not engage with ratchet 54. A cord 61 has one end thereof connected with pawllifter 57 and extends around sheaves or pulleys 62 62, the other end thereof being connected with one of the uprights 71. A ball or roll on the pattern-chain raises patternlever 51 and causes controlling-lever 31 to assume the position in which it is shown in the drawings, thereby holding clutch 35 upraised and disconnected and allowing clutch 34 to occupy its lowered and engaged position. A plain link of the pattern-chain allows the pattern-lever to descend and shifts the position of the controlling-lever 31, thereby allowing clutch 35 to descend and become engaged and raising clutch 34, so as to disengage the same. The pattern-chain 59 is advanced a step only when the lifting of the upright with which cord 61 is connected causes the depression of pawl-lifter 57. The pattern-lever 51 and corresponding end of lever 31 may be allowed to descend through gravity, or, if desired, a spring 481 may be employed, (see Fig. 4,) in which the said spring is shown applied to stud 43, one end thereof being engaged with a collar 47 on said stud and the other with lever 31..
